Title: Remote maintenance support system for plant
Inventor: HANIYUDA TAKEJI
IPC: G05B15/02
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To shorten the maintenance time of a control device by performing the investigation of cause and the support of repair from a remote place other than a plant when the control device or the like within the plant fails. SOLUTION: A data collection device 120 collects each signal in an alarm generation such as dip pipe control device alarm output signal (i), recirculating flow control device alarm output signal (h), failure display signal (j), dip pipe control failure display signal (k) or the like in the data collection part of the device 120. This system has a means for setting the device 120 for inputting the maintenance information related to a control device where a failure has occurred to the power plant side on the spot and transmitting the maintenance information to a maintenance center or the like in a remote place, and a means for setting a data transmitter-receiver 121 for receiving and displaying the maintenance information from the power plant to the remote place side.  The device 120 receives the maintenance information and alarm output signal from each control device including the control device set within the management area of a nuclear power plant and selectively transmits the maintenance information where the alarm is issued to the remote place.

Title: Magnetic sound recording and reproducing device
Inventor: KOSAKA TOMOAKI
IPC: G11B20/04
Filed: 1982-12-28
Abstract: PURPOSE:To realize the recording/reproducing with high fidelity, by giving an automatic control to the level of a recording signal with the output of comparison after comparing the reproduced signal of the 1st reference signal with the level of the 2nd reference signal and assuring an accurate control to each magnetic tape. CONSTITUTION:The reference of the 1st reference signal producing circuit 2 is processed by an encoder 5 and then recorded to a magnetic tape 9 via a control circuit 6, a recording amplifying circuit and a magnetic head 8. The recording signal is delivered via a magnetic head 10, a reproducing amplifier 11, a decoder 12 and an amplifier 13. On the other hand, the output of the decoder 12 is supplied to a comparing circuit 15 and compared with the 2nd reference supplied from the 2nd reference signal producing circuit 16. The circuit 15 gives an automatic control to the circuit 6 so that the 1st reference signal is set at a prescribed level indicated by the 2nd reference signal. At the same time, the 1st reference signal reaches the circuit after the 2nd reference signal with a delay equivalent to the time during which the tape 9 travels between the heads 8 and 10. Thus the recording signal is never controlled to a wrong level.

Filed: 1990-08-29
Abstract: PURPOSE:To restart the system at a high speed by sending an active request to a subordinate station only being inactive at a current point of time and requiring the active request to the said subordinate station at the restart after an exemption takes place in a control station. CONSTITUTION:When an exemption takes place in a control station 1 and the system is restarted, a state setting means 11 of the control station 1 outputs a subordinate station state setting request to an input output means 12. A state notice means 22 informs the content of a communication management table 23 to the input output means 12 of the control station 1. The input output means 12 gives the received information to a state comparison means 14 and compares the content of the communication management table 23 with the content of a subordinate state setting table 13 and gives the information to the state setting means 11 as to a subordinate station only being inactive at a current point of time and requiring the active request. A communication control means 21 gives an active request to the designated subordinate station.

Title: Heat transfer tube for heat exchanger
Inventor: HASHIMOTO KATSUTO
IPC: C04B35/565
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To realize a heat transfer tube for heat exchanger which can be stably used for a long period of time in a thermal decomposition gasification melting furnace used in a thermally heard environment by forming a tubular heat transfer tube being opened at least at one end and used for a heat exchanger by using a porous ceramic obtained by mixing various types of particles in which each particle is mainly constituted of the crystal phase of SiC and each type of the particles has a specified average particle size. SOLUTION: Particles having an average particle diameter of 5 to 10 μm and particles having an average particle diameter of 0.5 to 1 μm are mixed in the ratio of 1:9 to 3:7. The strength is improved by mixing two types of particles having different average particle sizes. Further, in the case that SiC mainly constituted of the crystal phase of SiC used, a thermal conductivity of >=50 W/m.K is realized and the obtained porous ceramic is excellent in the oxidation resistance under a high temp. oxidizing atmosphere, e.g. when the porous ceramic is heatd to 1,200 deg.C, the amount of the increase in the oxidation is as small as <=0.5%.  Moreover, direct oxidation of SiC can be inhibited by forming a dense SiO2 protective coating film having a cristobalite-type crystal structure on the surface of the porous ceramic, because the SiO2 coating film contributes as an oxidation inhibiting film of the SiC being the base material.

Title: Flow pump
Inventor: DOBLER KLAUS DR
IPC: F02M37/04
Filed: 1997-08-25

Title: Robot action control method
Inventor: SHIRAE TAKASHI
IPC: B25J9/16
Filed: 1989-09-05
Abstract: PURPOSE:To control an orthogonal action by applying the inverse transform to the shift extent of the orthogonal coordinate value for each interpolation in order to obtain the shift value of a robot axis and obtaining an error against the orthogonal coordinate value via the forward conversion of the robot coordinate axis to add this error to the next interplating shift value. CONSTITUTION:When an action arm 6 of a flexible arm robot 1 is linearly moved to an end point P2 from a start point P1, the distance between both points P1 and P2 is interpolated for calculation of the orthogonal coordinate value at a passing point of Pn. Then an inverse transformation formula is produced for the differential value to be used for transformation of the orthogonal coordinate value into the robot axis coordinates. Thus the shift value of a robot axis is obtained. Then the forward transform is applied to the robot axis coordinates to obtain an error against the orthogonal coordinate value shift extent. This error is added to the next interpolating shift value. As a result, an orthogonal action is controlled even with a complicated robot to which the adverse conversion formula cannot be produced.

Title: Abnormal signal pending system
Inventor: SHIRAIWA TOSHIYUKI
IPC: G08B25/00
Filed: 1988-09-14
Abstract: PURPOSE:To reduce misjudgments of the priority of abnormality in a building administration center by pending an abnormal signal which is already handled and need not be indicated by a building administration system. CONSTITUTION:When abnormal signal pending operation is performed, a local controller 40 sends an address code given to the controller 40 to a main controller 30 together with an input facility code, adds time information and an object code, and sends an abnormal signal pending request signal to the building administration center 1. A controller in the building administration center 1 sends back the abnormality signal pending request permit signal to the controller 30 through a CPU 10 together with its address code. Consequently, even if an abnormal signal is inputted to the controller 40 from a facility monitoring device 56 through a local monitor and control bus 53, the signal is not sent out to the controller 30 on condition that the signal coincides with abnormality signal pending facility information stored in a RAM 48.
